Evidence for surface loading as trigger mechanism of the 2008 Wenchuan earthquake

(July 14, 2010) Abstract: Two and a half years prior to China’s M7.9 Wenchuan earthquake of May 2008, at least 300 million metric tons of water accumulated with additional seasonal water level changes in the Minjiang River Valley at the eastern margin of the Longmen Shan. This article shows that static surface loading in the valley induced Coulomb failure stresses on the nearby Beichuan thrust fault system at <17km depth.

To little surprise, environmental programs at Three Gorges are falling short

(July 5, 2010) As the environmental problems continue to plague the massive Three Gorges dam, officials are falling way behind on programs to contain the pollution caused by its construction. Less than a fifth of the “water environment” programs laid out in a ten year plan in 2001 have been completed, while all nine of the projects to control pollution from ships have not begun, according to Vice-Minister of Environmental Protection Zhang Lijun.

Responding to Graeme Kelleher

(June 22, 2010) In his interview with chinadialogue’s editor, Isabel Hilton (In defence of dams, May 27), engineer and water-resource expert Graeme Kelleher says critics of China’s Three Gorges dam should accept the “facts” that the dam protects the environment by reducing coal burning and “saves thousands of Chinese people from being drowned in the floods of the Yangtze River every year.”

Huang Wanli’s predictions for the Three Gorges come to pass

(June 12, 2010) Huang Wanli, renowned hydraulics engineer and Tsinghua University lecturer, first voiced his opposition to the large-scale damming of rivers by opposing the construction of the Sanmenxia dam in 1957. In the 1980s he became a vocal opponent of the Three Gorges project and contributed to Yangtze! Yangtze!, the important critique of the dam compiled by China’s celebrated investigative journalist, Dai Qing. Now, as the Three Gorges dam is beset by monumental operational problems, Huang Wanli’s prescient analysis helps explain why it was a mistake to build the biggest dam in the world.
